i echo some data in the Author Box of my Wordpress Theme with:
<?php echo $user_info->new_user_blond; ?> <?php echo $user_info->new_user_brown; ?> <?php echo $user_info->new_user_red; ?>
The users can check one ore more checkboxes. If a user checks all 3 Checkboxes for example the result shows up in the author box as:
blond brown red
Everthing works fine, but please help me to change my code to achive this result:
blond, brown, red
When i put a "," between the codes it shows me the desired result. BUT if a user
only checks on checkbox it shows me:
blond,,
I would be very pleased if you would support me :)
<?php
$userarr = array(
$user_info->new_user_blond,
$user_info->new_user_brown,
$user_info->new_user_red,
);
$result = implode(',',array_filter($userarr));
echo $result;
?>

Can anyone help me get the value of IFC/USD 0.00001031 from the webpage http://infinitecoin.com.
I need to grab the value after IFC/USD..
The way I thought to do it was to:
$file_string = file_get_contents('http://infinitecoin.com');
preg_match('/IFC/USD plus next 11 charecters', $file_string, $title);
$value = $title[1];
echo $title_out ;
But im not sure how to ask PHP to find IFC/USD then return the next 11 characters after that.
If I could accomplish this, my task would be solved..
Any help would be great.
Thank you
Jason
$output = array();
preg_match("/(?<=IFC\/USD\s)[\d\.]+/", 'IFC/USD 0.00001015', $output);
$output will look like this:
Array
(
[0] => 0.00001015
)

My PHP code dosnt seem to be working and I dont Know Why when Ever I Use this code it will Make The whole webpage appear white.I think the problem is Here Somewhereecho Hello, (.$_SESSION['username'], ENT_QUOTES, 'UTF-8');Thanks In Advance
session_start();
if(!isset($_SESSION['user']) && empty($_SESSION['user'])) {
echo '<b>Log In</b>';
}
else {
echo Hello, (.$_SESSION['username'], ENT_QUOTES, 'UTF-8');
echo '</br></b>';
echo '<b>Log Out</b>';
}
When your page goes white, it usually means you have a fatal error in your code and need to check your logs, or turn on error_reporting.
In this case you're missing quotes, have the concatenation a bit messed up, and appear to be missing a function call (probably htmlspecialchars).
Also, you're checking $_SESSION['user'] a few lines before in your code, are you sure you don't mean to echo that here instead of $_SESSION['username']?
I think you want to change that line to:
echo "Hello, " . htmlspecialchars($_SESSION['user'], ENT_QUOTES, 'UTF-8');

Try with htmlentities like

?>
Follow this LINK
You can also make use of htmlentities()
<?php
echo htmlentities("<tr></tr>");
?>
Try this
$output = htmlspecialchars("<tr></tr>", ENT_QUOTES);
Use htmlentities
<?php
echo htmlspecialchars('<tr></tr>');

I need to echo a paging function twice,
echo blaetterfunktion($seite, $wieviele_seiten);
content
echo blaetterfunktion($seite, $wieviele_seiten);
I guess that would burden the server twice?
What can I do to have the server burdened just once and still echo it twice?
Place the result of the function in a variable:
<?php
$result = blaetterfunktion($seite, $wieviele_seiten);
echo $result;
?>
content
<?php
echo $result;
?>
Save it to a variable:
<?php
$variable = blaetterfunktion($seite, $wieviele_seiten);
echo $variable;
?>
content
<?php
echo $variable;
?>
